Merge the `use` parts of the `no_std` branch. This reduces the diffs between master and the `no_std` branch, making it easier to maintain. Most of these changes are derived from patches by @lachlansneff in https://github.com/Cretonne/cretonne/tree/no_std.
This crate contains the core Cretonne code generator. It translates code from an intermediate language into executable machine code.
